We are starting beta tests of WpfDiagram 2.5. The new features are:

Swimlane layout
SwimlaneLayout can be used to arrange process diagrams in which nodes representing activities are placed in swimlanes representing resources. The index of the resource allocated to an activity should be assigned to the corresponding node's LayoutTraits[SwimlaneLayoutTraits.Lane].

By default, the algorithm works with the diagram's LaneGrid, but its SwimlaneGrid property can be set to any class that implements ISwimlaneGrid. This allows applying the layout to a custom-drawn grid rendered through the DrawBackground event, or one composed of locked background nodes.


CascadeLayout algorithm
CascadeLayout places vertices on a virtual grid and arranges edges orthogonally, such that if the source graph is planar it is guaranteed that all edges will have no more than two bends and will not intersect.


TriangularLayout algorithm
TriangularLayout places vertices on a virtual grid, such that if the source graph is planar it is guaranteed that all edges will have a single segment and will not intersect. If the graph is not planar, the intersecting edges are optionally segmented and bended in order to improve readability.


HierarchicalLayout algorithm
HierarchicalLayout places vertices on predefined levels, such that if the source graph is level-planar it is guaranteed that all edges will have a single segment and will not intersect.


OrtogonalLayout improvements
OrtogonalLayout results have been greatly improved for nonplanar graphs.

Swimlane extensions
~ The lane grid can be printed by setting PrintOptions.EnableLanes = true;
~ The text of lane headers can be edited by the user if LaneGrid.AllowInplaceEdit is enabled;

If anyone is interested in trying the beta, please download this archive, which includes updated assemblies and help file:

Hi Amosius,

Try editing the project's licenses.licx and set PublicKeyToken=null at the end of the diagram's line. Then it should work for any version of the assemblies. We'll release it on Friday if we don't find any bugs by then.

I hope that helps,
Stoyan

Will this release also fix the printpreview method?

This was your earlier comment:

"We add [SecuritySafeCritical] attribute to such methods but haven't noticed PrintPreview requires it too. We'll have a new release in a few days and will add the attribute there."

Right now our diagram will not allow users to print because of this problem.

Thanks... I don't get the error i was getting when trying to printpreview.

But, is there a way to prevent it from splitting my node across a page break?  I am using tablenodes with a set number of rows, and when one of them appears at the bottom of a page it is split.

Also, with this build, my export to PDF and WMF do not work.  I get most of the text, but, my table nodes are messed up.

That fixed the printing and the export problem.

But, now the  text inside of my tablenodes no longer fits on the rows as it did before.  Even if i adjust the fontsize it seems to ignore it and the text looks larger than it did before.  It is also larger than the text in my other nodes.

I also have a message at the top of the diagram that says Midnfusion.Diagramming 2.5 beta.

Thanks...

As of now, it seems  to be working.

Now we see the text box remains behind the headers if HeadersOnTop is set to true - is it enabled in your project? For now you could toggle it from the EnterInplaceEditMode and LeaveInplaceEditMode handlers to make sure the text box is visible.
